ENVELOP FOR CIRCULAR-LETTERS.

Specication of Letters Patent.

Patented Aug. 25, 1914.

Application led March 26, 1912. Serial No. 686,424.

To all whom t may concern:

Be it known that I, GEORGE E. SHARP, a`

citizen of the United States, residing at Earned, in the county ofPawnee and State of Kansas, have invented certain new and usefulImprovements in Envelops for Circular-Letters, of which the following isa specification, reference being had therein to the accompanyingdrawing.

This invention relates to envelops and has special reference to anenvelop adapted to be closed without the use of any adhesive materialfor eiiecting such closure.

The principal obj ect of the invention is to improve and simplifythegeneral construction of such envelops.

With the above and other objects in view, the invention consists ingeneral of certain novel constructions, arrangements and combinationsof' parts, as will be hereinafter fully described, illustrated in theaccompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and: Figure lis a face view of an envelopconstructed in accordance with this invention. Fig. 2 is a rear viewthereof. Fig. 3 is a section on the line 3-3, Fig. 2.

In the form of envelop shown in Figs. 1,

2, and 3 an oblongblank is provided which is folded about the middle oi'its length to iorm a front 10 and a back 11. The edges of this blank areprovided with lateral extensions which are folded over the back toprovide side 'liaps 12. The end ofthe blank is also provided with atrapezoidal extension to form a closure iap 13. Extending from thistrapezoidal closure flap is a tongue 14 and the flap is provided with aslit 15. This tongue is preferably made from a stier material than thebody of the envelop and is passed up through the slit 15, being glued tothe iap 13 when made of different material, or formed integral therewithwhen made of the same material as the envelop. Furthermore, the tongueprojects upward slightly above the mouth of the envelop when the lat#ter is closed. In closing the envelop `the 4flap 13 is tucked inside inthe ordinary manner but when it is desired to open the envelop thetongue 14 is grasped and drawn open when the closure 13 will readilyslip out of the month of the envelop leaving the latter free.

There has thus been provided a simple and eiiicient device of the kinddescribed and for the purpose specified.

Having thus described the invention, what is claimed as new, is

An envelop comprising a body portion having an open end, a closure iiapextending :trom the open end of said body portion and provided with atransversely extending slit and adapted to be placed within the open endof the body, and a tongue carried by and extending from the end of theclosure flap in alinement with said slit whereby the tongue may bedoubled back upon the flap with its free end passed through the slit andextending beyond the end of said body portion when said closure flap isplaced within the body portion. I

In testimony whereof I hereunto ailiX my signature in presence of twowitnesses.
